Question

How do you graph the line `y = 3/5 x - 2`?

Answer 1

Please see below.

Explanation:

Take the equation `y = 3/5 * x -2` and pick 2 values of x at random and plug them in to find the corresponding value of y. For example, I choose 0 and 5.

x = 0:
`y = 3/5 * 0 -2 = -2`

So this calculation gives you a point on the plot of the equation `y = 3/5 * x -2`
The point has coordinates (0,-2), put a dot at (0,-2).

If you need help placing the point (0,-2) on your graph, click this link.

x = 5:
`y = 3/5 * 5 -2 = 1`

So this calculation gives you a point on the plot of the equation `y = 3/5 * x -2`
The point has coordinates (5,1), put a dot at (5,1).

Because there are no exponents in the equation, the equation plots a straight line. Draw a line through your 2 dots.

I hope this helps,
